An example Android application to control home light (power on/off).
I wrote this project to control my demonstration stand on the iVolga-2018 young people forum.
It is communicating with a private MQTT Server. A configured ESP8266 module that connected with the MQTT Server listens to the commands from the application. Also all sent commands store in InfluxDB database and a Grafana system visualizes them.
I use QNetworkAccessManager and QJsonDocument for getting and parsing some data from the InfluxDB server.
The project fully includes internal QtMqtt library. It is not right, but it works.
